A nurse is creating a plan of care for a child who has sickle cell anemia. Which of the following interventions should the nurse include in the plan?

Choice A reason: Continuing to monitor the client is not the best action, as it does not address the low urine output of the child. The child has a urine output of 20 mL/hr, which is below the expected range of 30 to 40 mL/hr for a 3-year-old child. Low urine output can indicate dehydration, kidney injury, or urinary tract obstruction, which require prompt intervention.

Choice B reason: Performing a bladder scan at the bedside is not the most appropriate action, as it is not the first-line diagnostic tool for low urine output. A bladder scan is a noninvasive ultrasound device that measures the amount of urine in the bladder. It can help detect urinary retention, which is the inability to empty the bladder completely. However, urinary retention is unlikely in a 3-year-old child, and a bladder scan may not be accurate or reliable in children.

Choice C reason: Providing oral rehydration fluids is the best action, as it can help restore the fluid and electrolyte balance of the child. Oral rehydration fluids are solutions that contain water, sugar, and salt in specific proportions that match the body's needs. They can prevent or treat dehydration, which is a common cause of low urine output in children. The nurse should offer the child oral rehydration fluids every 15 to 20 minutes, and monitor the urine output, vital signs, and hydration status.

Choice D reason: Notifying the provider is not the first action, as it is not the most urgent or effective intervention for low urine output. The nurse should notify the provider after providing oral rehydration fluids and assessing the child's response. The nurse should also report any signs or symptoms of dehydration, such as dry mucous membranes, sunken eyes, poor skin turgor, or lethargy. The provider may order further tests or treatments, such as blood tests, urine tests, or intravenous fluids.

Choice A reason: Subcutaneous insulin is not the preferred route for a client with DKA, as it has a slower onset and peak than IV insulin. IV regular insulin is the preferred route, as it provides a rapid and continuous infusion of insulin that can be titrated according to the blood glucose level.

Choice B reason: IV regular insulin is the medication of choice for a client with DKA, as it lowers the blood glucose level and reverses the ketosis and acidosis. IV regular insulin has a rapid onset and peak, and can be adjusted based on the client's response.

Choice C reason: IV potassium chloride is indicated for a client with DKA, as the client is at risk of hypokalemia due to osmotic diuresis, insulin therapy, and metabolic acidosis. IV potassium chloride can prevent or treat hypokalemia and its complications, such as cardiac arrhythmias.

Choice D reason: Oxygen via nasal cannula is not necessary for a client with DKA, unless the client has signs of hypoxia or respiratory distress. The client's deep and rapid respirations are a compensatory mechanism for the metabolic acidosis, and do not indicate a need for oxygen therapy.

Choice E reason: Sodium bicarbonate is not recommended for a client with DKA, as it can cause paradoxical cerebral acidosis, hypokalemia, and impaired oxygen delivery. The client's acidosis can be corrected by IV insulin and fluid therapy, which will restore the normal metabolism of glucose and ketones.
